Embodiment Construction
[0042] The technical solution of the present invention will be further described in more detail below in conjunction with the drawings and specific embodiments.
[0043] Please refer to figure 2 As shown, it is a schematic diagram of the architecture of the present invention. The digital photography device 200 with brightness compensation includes: a light metering unit 210, a photosensitive component 220, a light source generator 230, a dimming circuit 240, an arithmetic unit 250, and a storage unit 260.
[0044] The light metering unit 210 is arranged on the outside of the digital photography device 200. The light metering unit 210 is used to sense the external brightness of the digital photography device 200. In this embodiment, the external brightness of the digital photographing device 200 refers to the environmental brightness during shooting, and may also be the environmental brightness of the shooting target. The photosensitive component 220 is used to capture multiple f...

The invention discloses a digital photography device with the brightness compensation function, and a compensation method thereof, which are applied to the brightness compensation during the shooting process of the digital photography device in different light sources to maintain the frame rate of the digital photography. The digital photography device comprises a light sensing unit, a light sensing component, a light source generator, a light dimming circuit, an arithmetic unit and a storage unit, wherein, the light sensing unit is used for sensing the brightness outside the digital photography device; the light dimming circuit is electrically connected with the light source generator; the light dimming circuit is used for controlling the illuminating brightness of the light source generator; the arithmetic unit is electrically connected with the light sensing unit and the light source generator; and the arithmetic unit executes a brightness correction method and a brightness compensation method, the brightness correction method is used for correcting the brightness sensing reference value of the light sensing unit, and the brightness compensation method is used for adjusting the brightness of the light source device according to the external brightness of the digital photography device.
Description
Technical field [0001] The present invention relates to a method for adjusting shooting parameters of a digital camera device, and in particular to a digital camera device and a method for brightness compensation thereof for maintaining the frame rate of a digital image for brightness compensation of the digital camera device shooting in different light sources. Background technique [0002] With the development of digital imaging, in addition to using digital cameras to record the images users want, digital photography devices can also be used to shoot dynamic videos. The video taken by the digital camera can be regarded as composed of multiple pictures. When the ambient brightness permits, generally, the shooting frame rate of the digital camera is 30 frames per second. Of course, the higher the 120 frame rate, the smoother the playback quality. If the frame rate of the shooting is too low, it will cause the video playback to have skips. In other words, the film will be skip...
